According to TMZ.com, Kim included a clause in her pre-nup that requires her to buy back the ring from Kris for its original price if the two divorce. Without the clause, it seems, Kim would have been allowed to keep the ring, no payment necessary.

Kris Jenner, for one, thinks the ring should remain Kim's free of charge. The Kardasian "momager" appeared on "Fox and Friends" on Thursday, declaring, "That's between them -- a gift is a gift. If you look at the etiquette books, it says keep a present."
